When to Call vs. When to DIY: HVAC Decision Guide
```html
Picture this: a Thursday at 8:42 a.m., you're two blocks east of Biscayne Blvd on NE 123rd St, and the TPMS light comes on. Your spare is flat. You pull over, check the pressure, and it's 22 PSI — way below the 32 PSI minimum. Now what? Do you try to drive on it? Call a tow truck? Or can you fix it yourself?
If your spare is flat, you can try to fix it yourself by adding air in 10 PSI increments until it reaches 32 PSI. But if you don't have a tire pressure gauge or air compressor, or if the tire won't hold the pressure, you should call a professional. Aventura HVAC Maintenance can help with your HVAC needs, but not with flat tires.
Why does my spare tire go flat so fast?
Your spare tire is a different size and shape than your regular tires, so it wears out faster. It's also stored in the donor bay, which is exposed to the elements. The heat, humidity, and salt air in South Florida can cause your spare to lose pressure faster than your regular tires. Plus, if you've ever had a blowout, you know how quickly a tire can go flat.
Tires lose roughly 1 PSI per month, so if you haven't checked your spare in a while, it's probably lost some pressure. The TPMS light comes on when the pressure drops below 32 PSI, but by then, it's already too late. You need to check your spare tire pressure regularly, especially if you live in a hot, humid climate like South Florida.
How do I know if my spare is safe to drive on?
If your spare is flat, it's not safe to drive on. Even if you add air to it, it might not hold the pressure. A flat tire can cause a blowout, which is dangerous and can lead to a crash. If you're not sure if your spare is safe, it's better to call a tow truck and get a new tire.
You can check your spare for any signs of damage, like cuts, bulges, or cracks. If you see any of these, it's not safe to drive on. You should also check the tread depth. If the tread is worn down to the legal limit, it's not safe to drive on. Aventura HVAC Maintenance can help with your HVAC needs, but not with flat tires.
Can I fix a flat spare tire myself?
If you have a tire pressure gauge and an air compressor, you can try to fix a flat spare tire yourself. First, check the pressure. If it's below 32 PSI, you can add air in 10 PSI increments until it reaches 32 PSI. Make sure to check the pressure again after a few hours to see if it holds.
If the tire won't hold the pressure, it's not safe to drive on. You should call a tow truck and get a new tire. Aventura HVAC Maintenance can help with your HVAC needs, but not with flat tires.
